3 SHBETSSHEET P WITNESSES c. on

To all whom it may concern Be known that I, HARLEY C. ALGEB, citizen of the United States, residing at Chi: cago Heights, in the county oE Gool: State of Illinois, have invented a new anti useful Recorder, of which the following is specification.

My invention relates to improvements recorders in which a record or indication is made by a suitable recording element upon any suitable record sheet or indication receiving means, the object being provide a recorder for indicating, registering or recording the performance of two or more re: riable factors in such a manner as to recorri the result of a mathematical calculation, such for example as the quotientobtained by dividing one factor by another factor, or the product obtained by the multiplication of factors, any or all of which factors may be variable.

'l he recorder may be constructed to record the result of a mathematical calculation for a number of different purposes, such as to record the weight of coal burned per horsepower hour in a power plant, the amount of ammonia produced per ton of coal consumed in a gas plant where ammonia is a by-prodnot, the number of cubic feet of gas per ton of fuel consumed, the evaporation of boilers in pounds of water evaporated per pound of fuel burned, or like results. l have below described in detail the construction of such a device which may be used "for recording evaporation of boilers and the like although I do not confine myself to the use of my in vention for this purpose.

The invention consists in certain novel constructions which are described below and which will be more particularly pointed out in the claims.

The managers oi? many power plants today realize the advantage of having continu ous and automatic records showing the performance of the power plant and among the most important items which may be recorded are the iuelwhich is burned and the water that this fuel converts into steam or the steam produced. Recorders have been made which record the llow of water or steam or which register the total amount of water "i- 'r '7- avg innit: on).

passin through the pipe line such as the boiler reed line leading water to the boilers recorders have also been made which antomatically record or register the coal, gas, oil or other fuel used. A more important factor which is the result of the two factors just mentioned, is the evaporation, which may be defined as the quantity of water evaporated or the quantity of steam produced divided by the quantity of fuel burned and in obtaining this evaporation it has been necessary to obtain the amount of water evaporated or the quantity of steam produced in a given time from one recorder or register, the amount of fuel burned in this period from another recorder'or register and then calculate the evaporation by dividing the amount of water evaporated by the amount of fuel burned. For example suppose that an engineer is conducting a test upon a boiler and that he wishes to know the evaporation up to that time so that he may have an indication of the progress of the test. Heretofore it has been neccssaryfor him to obtain the weight of fuel consumed from a fuel meter or a record of weights if the weighing is done by hand and then to divide the former by the latter in order to obtain the weight of water evaporated per pound of fuel. It will be seen that my vice does this automatically and gives a record of this division all times so that a glance shows the evaporation thus giving a convenient record and doing away with the necessity of performing the calculation.

lln my invention 1 have produced anapparatus which automatically and continuously makes such a division and which indicates, registers or records the quotient of the factors, which may be variable. The apparatus described may be used to record evaporation or it may also be used to record other mathematical results if desired. When used to re cord evaporation of boilers it is usually sutiicient to record the actual evaporation which is the actual pounds of water evaporated or steam produced divided by the number of pounds o fuel burned for this purpose without regard to the temperature of the boiler feed water or the pressure under which the boilers are operating. in

some cases it is desirable to reduce the actual evaporation to a common basis for comparison such as the equivalent evaporation from v and at 212 degrees Fahrenheit which takes into account the temperature of the boiler feed water and the pressure under which the boilers are operating, in whi'chcase the actual evaporation should be multiplied by the so-called factor of evaporation to give the equivalent evaporation desired and in such cases I provide means for producing this re sult automatically.

Figure 1 shows an elevation of my invention adapted to record actual evaporation; Fig. 2 shows a plan view of Fig. 1, a portion ofthe frame Work of Fig. 1 being removed to better show the mechanism below; Fig. 3 shows a modification of the recorder in connection with a Water meter and a coal meter; Fig. 4 shows a front elevation ofa modification of my invention while Fig. 5 shows a side view of Fig. 4.

In Fig. 1, I have-shown the mechanism as arranged to record actual evaporation, mounted on a suitable support 1. The mechanism is preferably i'nclosed in a case 2, Fig. 3 the mechanism being shown in Fig. 1 with the case 2 removed. Any of the many forms of indicating members such as a counter or register, a recording chart or a scale, may be used for indicating the evaporation. lit is preferable in many cases, how- "ever, to employ a recording member operated by clockwork or similar mechanism and in Fig. l I have shown the indicating member of the recording type. This recording member which may be of the disk, drum or any other type desired, (a drum 3 being shown) is carried by suitable means such as a shaft 4': which is rotatably mounted in a suitable bearing, 5. I carried by brackets 7 and 8 extending from the support 1 may be arranged to rotate the drum, 3 from one end of the shaft 4, 4t. Upon the drum 3 may be mounted a chart 9 adapted to receive the record. A chart or record sheet 9, carried by the drum 3 may he graduated or may have divisions marked thereon which indicate the amount of the evaporation. A recording member may be provided for indicating or recording upon the chart 9 and such recording member may be made movable up and down. Any preferred form of record sheet may be employed or any other suitable means used to indicate the result which may preferably be shown upon a graduated member marked with figures or other notations. If a stationary scale is provided instead of a. movable chart the result is indicated but not recorded, in which case a pointer may be used in theplace of the pen 36 while if a chart driven by clockwork is used the result is not only indicated but is also recorded as the chart moves. Mechanism may then be pro- A suitable clockwork 6' 1,1ao,ase

vided which may be actuated by the action of a water meter or weigher or steam meter to cause the indicating member to rise as more water is fed to the boilers, thus indicating a higher value, while such mechanism may also be actuated by a fuel meter or weigher to cause the indicating member to lower thus indicating a lower value upon the chart 9. The indicating member will then be actuated in accordance with the amount of steam produced, but with constantly decreasing increments, to indicate a higher value and will be actuated in accordance with the amount of fuel consumed, with constantly decreasing increments, to indicate a lower value whereby the value actually indicated may represent the evaporation of the boilers. The recording member then tends to move in one direction in accordance with increase in value of one element or material delivered past a given point, while it also tends to move in the opposite direction in accordance with increase in value of another element or material delivered past a given point so that the recording member records a resultant of two motions which, by suitable proportioning of the mechanism, may be made to correspond to the evaporation, if desired. ll do not confine myself to any particular construction or mechanism for producing this result but in the various drawings have shown mechanism which may be employed.

In Fig. 1 is shown a sliding framework or carriage comprising a suitably arranged top member 10 which may be secured to a suitable bottom member 11 by means of tubes 12 and 13, and which may carry a revoluble drum 14; having a shaft 15, 15 which may be rotatably mounted in a suitable bearing 16 carried by the bottom member 11. At one endof the shaft 15 is secured a ratchet wheel 17 and a suitably mounted electro-magnet 18 secured to top member 10 and having an armature 19 secured to a pivoted arm 20 operates through a pawl 21 to move the ratchet wheel 17 at intervals when an electric circuit through the electro-magnet 18 is closed. A suitable spring 22 in tension, secured to the arm 20 and pawl 21 holds the pawl 21 against the ratchet wheel 17. W'ires23 and 24 lead from the electro-magnet to a battery 25 or other source of electrical energy and to a contact maker comprising a base 27 with contact arms 28 and 29 which may be of flexible spring construction. The contact arm 28 is movable and may be suitably connected to a machine which registers or records one of the elements or one of the factors of the final quotient or product which it is desired to record uponthe chart 9.' F or example, the. movable contact arm 28 may be suitably connected to the registering device of a water meter so that the arm 28 makes conare of such construction that they deliver water or fuel in a continuous stream and not in unit charges, connections may be made to operate the mechanism by electric contact which will produce the record with broken lines as just described or connections may be made to operate the mechanism continuously as shown in Fig. 3.

In Fig. 3 is shown a coal meter, which may be adapted for measuring and registering continuously the coal passing therethrough. Such a coal meter may comprise a tube or -pipe-63 in which is mounted a screw or vane 64- adapted to operate through a pair of. bevel gears 65 and 66, a shaft 67, and a suitable gear 68 secured to the shaft 67 maydrive a gear 69 of a suitable counter or register, 70 which may be adapted to register the quantity of coal passing through the meter. A pointed member 71 may be used to cause the coal to diverge above the screw 64 and as the coal passes down through the pipe 63 it will cause the screw 64 to revolve and the register 70 may be so adjusted as to register the number of cubic feet or pounds of coal passing through the ipe 63. The shaft 67 suitably supported y a bearing 72 on the support 1, may extend from the coal meter and operate through suitable gears 73 and 74 to turn the drum 37, which will thus cause the sliding frame work to lower continuously and in proportion to the amount of coal being delivered. In Fig. 3 is also shown a water meter 75 having a suitable inlet 76 and outlet 77 and a register 78 for indicating the amount of water passing therethrough. A shaft 79 suitably connected with the-registering mechanism 78 may extend from the water meter. The shaft 79 may be of flexible construction and adapted to connect with the shaft 15 of the revoluble drum 14. The shaft 79' being flexible will allow the sliding framework carrying the drum 14 to move up and down while at the same time causing the drum 14 to revolve and in pro portion to the amount of water passing through the water meter. The proportions of the gearing of the coal meter and ofthe mechanism driving the shaft '79, together with the pitch of the wires wound on the revoluble drums 14 and 37 may be made such that the pen will record the resultant evaporation upon the described.

'The apparatus as above described is intended to record the actual evaporation and as above mentioned my invention mayalso be adapted to record the equivalent evaporation which takes into account the'temperature of the feed water and the presure under which the boilers are operating. In Figs. 4 and 5, are shown modifications of my invention adapted for this purpose. In this case the drum 3 carrying the recording chart 9 as previously chart 9 may be carried by a suitable shaft 80 which is slidingly received in bearings 81 and 82 which may be carried by the support 1. The shaft 80 has an enlarged head 83, rotatably held by an eye 84 which may be suspended from a cord 85, 85 passing over a pulley 86 rotatably mounted on a shaft 87 carried by the support 1. The enlarged head' 83 allows the shaft ,80 to turn as the shaft 80 may be moved longitudinally. The shaft 80 carries a gear 88 with relatively long face which meshes with a gear 89 suitably connected to the clockwork 6 so that the clock work 6 operates through, the gears 89 and 88 and shaft 80 to turn the drum- 3 while at the same time the drum may be moved up or down, thus altering the relative position of the pen 36 onthe chart 9 causing the pen 36to record a slightly different value in proportion to the amount which the drum 3 is raised or lowered. Connectedto the end 85 of the cord passing over the pulley 86 is a sliding bar 90 slidingly received in guides 91 and 92 secured to the support 1. Suitable means may be provided for automatically raising or lowering the drum 3 thus altering the value of the record being made by the pen 36 in accordance with changes in terperature of the boiler feed water or changes in pressure under which the boilers are operating. In cases where the temperature is constant but the pressure varies, means may be provided operated by the pressure alone causing movement of the drum 3 to bring about the desired results. In cases where the pressure is constant and the temperature of the boiler feed water changes, means may be provided to alter the record of the pen 36 upon the chart 9 in accordance with the variation in change of temperature. In Figs; 4 and 5, I have shown mechanisms which may be used for these purposes. A disk 93 may be suitably mounted upon and secured to a shaft 94journaled in bearings 95 and 96. The bearings 95 and 96 are adapted to slide upon rods 97 and 98 carried by brackets 99, 100, 101, and 162 secured to the support 1, so that the disk 93 may be given an up and down movement while at the same time ro-v tating; a wire or projection 103 spirally wound may be secured to the face of the disk 93and the sliding shaft 90 may have an extending finger 104 adapted to engage the wire 103. Connected to a suitable thermometer 105' which may be adapted to indicate the temperature of the water passing through a pipe 106 which may lead to the' boilers, is a shaft 107 extending therefrom connected to the shaft 94 and adapted to rotate the disk 93 thus causing the extending finger 104 which engages the spirally wound wire 103 to be moved up or down thereby moving therecording drum 3. It is to be understood that the weight of the parts sus pended from the end 85 of the cord is enfhis meo eoo is causing an increase in the value the evaporation as recorded on the chart 9 as the hemper-abuse in the boiler feecl line 108 decreases. The shaft 107 may be of u flexible construction so that it will allow the disk 93 to move up or down While being rotslsecl. A reyoluble (lisl: 110 may be mounted upon and se cured to a she f-' u ill suitably joumalezl bearings 112 ancl 13.8 helol by she support 1. A suitable gage 114- conneccecl to the boilers as through a pipe 115 may be used indicate the PKQSSUTB Within "ehe boilees ancl o suitable shaft 116 may exbeiui from the gave 114 and be securecl the shaft ill so as "so rotate the disk 110 as the Pli-BSSUEG Within 25 the boilers changes. Upon the disk 110 is formed a spirally wounrl Wire or projgeclzion 117. A yoke 108 may be secured to the bearings 95 and 96 and may have a finger 109 extending therefrom and eil'apiteel to so 30 gage the spii'ally Wound Wire ll? so that motion may be iransmicteol through the exicmlinu linger 109, yoke 108 to the sliding beaeiugs 95 and 93 causing the disk 93 to be moved up or (lows allowing the slicling be? 90 to move up 0? flown which causes the drum 8 to lower of rise. The proportions 01' she "oasis of the gage 11 i and the shape of no spirally Wouno WHG ll? may be such has the rlrum 3 will be lowered, thus caus- 49 log a corresponcliug higher value too be T3- coided upon the recording char; 9 as the pressure Within the boilers rises.
